This is incredibly pertinent to something I'm writing now, trying to explain what feminism is to men who think they're against it. The point you make here--about how bro culture insists it should always be okay to express sexual interest to a woman, and how they think woman exist to fulfill men's sexual desires, and how a woman's sexual role is always at least as important as her professional role--this is what needs to be called out and not glossed over or mansplained away.
